HANGER TROLLEY-WIBES.

Specification of Letters Patent. Patented Sept, 15, 1914,

Application filed March 2, 1909. Serial No. 489,962.

To all whom it may concern:

Be it known that I, HERMANN Sorrt'rrrn, a

citizen of the Empire of Germany, residing in Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Hangers For Trolley-Wires, of which the following is a specification.

This invention relates to an improved hanger for trolley-wires, which is specially adapted for suspending the trolley-wire from a messenger-cable hanging in catenary curves, and more particularly to a hanger which provides for the free vertical motion of the conductor toward the messengercable by the special construction of the suspension-clip and the connection of the hanger-rod with the same, so that any friction with the cable and consequent chafing and injury of the latter is avoided, and a firm and reliable suspension device for the hangers of trolley-wires obtained; and for this purpose the invention consists of a hanger for trolley-wires which comprises a suspension-clip for the messenger-cable having a looped lower end and a hanger-rod having a loop-shaped upper end engaging the loop of the clip. The invention consists of a suspension-clip for the messenger-cable having a loop at the lower end, a curved seat at its middle-portion embracing the messengercable and upper projecting ends and means for clamping the ends of the suspensionclip together so as to firmly hold it on the cable.

In the accompanying drawings, Figures 1 and 2 represent respectively an end-elevation and a side-elevation of my improved suspension-clip for the hangers of trolleywires, arranged with clamping means for the messenger-cable at the upper and lower ends, Figs. 3 and 4 are respectively a sideview and an end-view of a modified construction of the suspension-clip and its clamping mechanism, Figs. 5 and 6 are respectivelya side-elevation and amend-elevation of the suspension-clip, showing a modi fied construction of the clamping mechanism, Fig. 7 is a plan-view of the suspension-clip shown in F ig. 5 with the-clamping-key removed, and Fig. 8 is a detail view of the clamping-key for the suspension clip shown in Figs. 5 and 6.

Similar letters of reference indicate cor-.

respqnding parts throughout the different figures.

Referring to the drawings, a represents the messenger-cable from which the hangers for the trolley-Wire are suspended by means of clips 6. The upper part of the suspension-clip is clamped to the messenger-cable and the lower loop-shaped part connected with the loop-shaped upper end al of the hanger-rod (.Z. vThe suspensionclip 5, shown in Figs. 1 and 2, is made of two cast metal sections which are provided near their upper ends with curved seats 5 that embrace the messenger-cable a, and which are firmly attached thereto by two clamping screw-bolts e, andnuts e the upper clamping-screw and nut e, e being attached to the upper projecting ends of the two clip-sections, while the lower ends are connected by the second clamping-screw and nute The curved seats I) are shaped so as to embrace the messenger-cable, the same resting on inwardly-projecting lugs b of the clip-sections. The loop-shaped upper end of the hanger-rod d rests on the raised annular portions d at the inner faces of the clip-sections. The suspension-clip b may also be made in one piece of U-shape which is bent up by suitable dies from sheet-steel, as shown in Figs. 3, 4, 5 and 6, the lower part being bent into convex shape so as to receive the loop-shaped upper end al of the hangerrod d. The middle portion of the clip 5 is made curved so as to form the seat 6} which embraces the messenger-cable. The upper projecting ends of the suspension-clip are connected by a clamping-screw-bolt and nut e 6 the head of the screw-bolt being held in position by an ear e ,.which is bent up at one side of the clip, while the screw-nut is held in position by a lip e which is bentup from the opposite end of the link, as shown clearly in Fig. 4. The bent-up ear e serves for preventing the turning of the screw-bolt when tightening the screw-nut, while the lip 6 serves for locking the screw-nut after it has been applied to the bolt 6 In Figs. 5 and 6 the suspension-clip b is clamped to the messenger-cable a. without the employment of a clamping-screw and nut, in place of which a wedge-shaped key f provided with bent over sides is employed, which embraces the upper outwardly-bent and tapering end 5 of the suspension-clip and presses them firmly together. One end of the clampingkey is provided w ith a downwardly bent lug or tongue, P which prevents the driving in of the key f at the wrong end and which serves as a stop for the key when driven home on the outwardly-bent upper ends of the key.

Any suitable hanger may be used in connection with the hanger-rod, preferably the hanger for which Letters Patent were granted to me, No. 909,691, dated January l2, 1909, only with this dilferen'ce that the injuring the messenger-wire by friction with the suspension-clip. The U-shaped clip spreads before it is applied to the messenger-cable to a sufiicient extent so that the loop-shaped end of the hanger-rod and the cable can be inserted in the same, upon which it is attached bythe clamping-screw and nut I or the wedge-clamp to the messenger-cable and firmly held in position thereon without chafing or injuring the same, while still permitting the hanger-rod and hangerto move freely in a vertical direction in the clip,

' under the pressure of the bow on the trolley- Wire.

Another advantage of the improved hanger is, that the horizontal displacement mit the conductor to of the trolley-wire is counteracted when the suspension-clip is clamped rigidly to the messenger. In case it is preferred that the trolley wire should be able to move under changes of temperature, the suspension-clip is notclamped tightly to the messengercable so as to slide along the same and perbe adjusted by a tensioning device. 7,

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. A hanger for trolleywires, comprising a loop-shaped link "for receiving the messenger-cable said link havingupwardly-projecting ends above the cable, .means for clamping said ends together, and a hangerrod provided with a loop-shaped upper end pivotally suspended "from the lower portion of the link and with means at its lower end for connecting it with the ear or clamp of atrolley-wire.

'2. A hanger for trolley-wires, comprising a loop-shaped link having inwardly-projecting portions forming a seat for the messenger-cable, upwardly-projecting ends above the cable, clampin means for the u er ends of the link, an a hanger-rod prov1 ed with a loop-shaped portion at its upper end pivotally connected with the lower end of the loop-shaped link and with means at its lower end for connecting it with the ear or clamp for the trolley-wire.

3. A suspension-clip for the hangers of wires, comprising a loop-shaped'body for re ceiving the loop-shaped end of the hangerrod, a curved middle portion or seat for the messenger-cable, and projecting upper ends one end being provided with a cut-out portion and the other with a lip, and a clamping screw and nut connecting the upper ends said bent-out portion and lip servmgfor locking the head of the screw-bolt and the screw-nut in position.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
